You have the specifications of the motors supplied by RepRapPro wrong. See [www.aliexpress.com] for the correct spec. This motor [www.omc-stepperonline.com] is a close match.
For the Duet (as with most other 3D printer electronics), you should choose motors with rated currents in the range 1.3 to 1.7A.
thanks a lot . i will order 5 of them .
